This allows dependent projects to run tests using Bazel. (Previously,
DiffRepository would give errors because Bazel has packaged the .xml
files it needs inside JAR files.)

Related to CALCITE-5346.

Previously we relied on the parser to map unrecognized datatypes to a known type using SqlAlienSystemTypeNameSpec. This worked but made it difficult to change or add new types as necessary. One would have to update at least 3 different parsers (babel, core, server) to make a change.

This change allows for declaring user-defined types at the root of a schema model and allows for easy type alias mapping. These data types are shared by all schema in the model so cast and DDL expressions do not need to scope data type references to a particular sub-schema.

For example:
```
inline: {
  version: '1.0',
  types: [
    {
      name: 'BOOL',
      type: 'BOOLEAN'
    },
    {
      name: 'BYTES',
      type: 'VARBINARY'
    },
...
  ],
```
Allows for `CAST("true" as BOOL)`
